Respirator

respirator

an apparatus for providing long-term artificial respiration

Respirator

a device that forces the delivery of a gas (air, oxygen, nitrous oxide) to the lungs and ensures the saturation of the blood with oxygen and the removal from the lungs of carbon dioxide gas.

The respirator is connected either to a mask placed on the patient’s face or to an intubator that is introduced into the respiratory tract. The AMBU and the “accordion” are respirators that are worked manually by the physician-anesthesiologist. The AMBU consists of a rubber or plastic pouch with valves at both ends. One valve admits air (oxygen) from outside into the pouch, and the second opens when the pouch is compressed and the gas is forced into the patient’s respiratory tract; exhalation occurs passively. The accordion apparatus forces exhalation as well. Respirators that operate on the basis of compressed gases (as a rule made of metal) are of two types: those that regulate the delivery of air by pressure and those that regulate it by volume. Pressure-regulated delivery (for example, in the DP-1) produces inhalation and exhalation according to the capacity of the lungs into which the gas is blown. When the lung capacity is decreased (with pneumonia, atelectasis), with a consequent increase in resistance, exhalation occurs more rapidly. Respirators that regulate the delivery of air by volume (for example, the Soviet RD-200) always deliver a fixed volume of gas, regardless of the condition of the lungs.

The most widely used in clinical practice are the Soviet electrical respirators that regulate the delivery of air by volume (RO-1, RO-3, RO-5) and permit the maintenance of a precisely fixed volume of delivered gas; when there is a change in a frequency of respiration (inhalation of gases) there is also a change in the per-minute volume of lung ventilation, while the respiratory volume remains constant (fixed). These respirators make for inhalation and exhalation of fixed duration and, by changing the pressure on exhalation, allow for the discharge of any remaining air from the lungs (for example, in bronchial asthma). In some respirators, such as the Engstrom and the AND-2, the perminute frequency lung ventilation is regulated independently of the per-minute volume of lung ventilation, which remains stable. The ROA-1 automatically maintains a per-minute volume of ventilation that provides the normal content of carbon dioxide in the exhaled (alveolar) gas. Respirators for auxiliary ventilation (when respiration is preserved) bring about supplementary inhalation when their volume is decreased (for example, in barbiturate poisoning). This apparatus is attached, as an independent unit, to other stationary respirators, such as the RO-3 and the RO-5.

Respirator

an apparatus that protects the respiratory organs from dust and harmful substances. Insulating (tubular or oxygen) respirators are used when the oxygen content of the air is insufficient (less than 16 percent) and when the air is highly contaminated, as during rescue operations at the site of accidents. Filtering respirators, which filter out dust, are lightweight and portable but less efficient than insulating respirators when the air is highly contaminated. Various fibrous materials, such as felt, cotton, corrugated paper, porous cardboard, and natural and synthetic fabrics, are used in respirators to filter out radioactive dust. Hood respirators and face masks as well may be used for this purpose.

The simplest respirator used in the USSR is the Shb-1 Lepestok respiratory mask, which consists of a filtering fabric between two layers of gauze. Widely used in factories and laboratories, this mask affords excellent protection and is very light, weighing about 10 g.

respirator

[′res·pə‚rād·ər] (engineering) A device for maintaining artificial respiration to protect the respiratory tract against irritating and poisonous gases, fumes, smoke, and dusts, with or without equipment supplying oxygen or air; some types have a fitting which covers the nose and mouth.

respirator

[res´pĭ-ra″tor] 1. an apparatus that qualifies air breathed through it, to be distinguished from a ventilator.2. frequently used misnomer for ventilator (def. 2).Drinker respirator a formerly common but now rarely used type of ventilator that provides controlled, automatic breathing for a patient whose respiratory muscles are paralyzed; it consists of a metal tank, enclosing the patient's body with the head outside, within which artificial respiration is maintained by alternating negative and positive pressure. It was instrumental in the treatment of the poliomyelitis epidemic of the early decades of the 20th century. Popularly known as iron lung.

Patient discussion about respirator

Q. Help her to breathe. My sixteen year old cousin (girl) who is wondering if she is suffering from asthma, anxiety or both. She is thin, healthy girl and have been very worried She have asthma and have been thinking about it constantly. When she exercise, she get more out of breath, more worn out, and her heart beats faster than other people. Sometimes her chest hurts, but people tell me that is from my chest muscles being worked. She get a little dizzy also. When she go to bed at night sometimes it seems hard to breathe. She can take a deep breath and everything but it seems hard or something. I know there isn't anything wrong with my heart because she had an EKG done recently and chest x-rays. That was fine. When it is hot humid and muggy outside she find it hard to breath. Do you think she have asthma. She don't have any coughing or any known wheezing. Could thinking about every breath she take seem like she have asthma? She really want to know and me too, what is going on! Please help her to breathe!!!!A. PS--alcohol and cigarettes can cause this problem to(drugs)mrfoot56.

Q. What causes bad breath? I have bad breath for a long time. What causes it?A. Here are some causes of bad breath:
A Dry mouth- Saliva helps cleanse and moisten your mouth. A dry mouth enables dead cells to accumulate on your tongue, gums and cheeks. These cells then decompose and cause odor. Dry mouth naturally occurs during sleep. It's what causes "morning breath." Dry mouth is even more of a problem if you sleep with your mouth open. Some medications as well as smoking can lead to a chronic dry mouth, as can a problem with your salivary glands.
Some Diseases can also cause bad breath- Chronic lung infections and lung abscesses can produce very foul-smelling breath. Other illnesses, such as some cancers and certain metabolic disorders, can cause a distinctive breath odor. Kidney failure can cause a urine-like odor, and liver failure may cause an odor described as "fishy." People with uncontrolled diabetes often have a fruity breath odor. Chronic reflux of stomach acids from your stomach (gastroesophageal reflux disease, or GERD)

Q. How to get rid of bad breath? My wife complains that I have bad breath. How can I get rid of it?A. Consider that candida infection can make your breath worse. You might try cutting down on sugar and carbs.
"Bad breath can also be caused by a candida (yeast infection), you may have a constant white furry tongue. Look at cutting down your intake of sugars and processed foods, as well as those containing yeast. - Search for Anti-Candida diet on a search engine for more info"
